+  This module defines the test case to be used by
+  channel tests.
+
+  Such tests rely on `Phoenix.ChannelTest` and also
+  import other functionality to make it easier
+  to build and query models.
+
+  Finally, if the test case interacts with the database,
+  it cannot be async. For this reason, every test runs
+  inside a transaction which is reset at the beginning
+  of the test unless the test case is marked as async.
